Origin
Coelopleurus mailardii is a deep-water sea urchin species, typically collected from deeper marine environments where fewer specimens are available compared to shallow-water urchins. Its rarity and structure make it especially desirable for collectors and scientific displays.
Appearance & Natural Features
Deep Water Sea Urchin shells are known for:
Compact, rounded test with fine surface texture
Subtle natural coloration (often pale cream to off-white when cleaned)
Symmetrical structure prized by echinoderm collectors
Delicate, refined form typical of deep-sea species
Each specimen is naturally unique in size, tone, and surface detail.

This rare sea urchin shell is ideal for:
Cabinet of curiosities displays
Scientific and educational collections
Marine biology reference specimens
Coastal and minimalist décor accents
Photography styling and flat-lay design
Specialty shell and echinoderm collections
Best suited for collector-grade display rather than heavy crafting due to its delicate nature.

Every seashell is a gift from the ocean, and I pack each one with the care it deserves, ensuring its safe journey to you.
Preparation Time: I will carefully wrap your seashells in recycled paper and twine within 1-3 business days, making it feel like a personal gift from the sea.
Shipping Method: I use reliable standard shipping and will provide you with a tracking number, so you can follow your shell’s journey.
International Orders: For shells traveling across oceans, please allow a little extra time. Sometimes customs checks can extend their journey.
The ocean never creates two identical shells, making the one you receive truly one-of-a-kind.
Damaged in Transit: If your shell is damaged during its journey, please contact me within 24 hours of receipt with a photo. I will immediately send a replacement or issue a full refund.
Not as Described: I do my best to represent each shell accurately through photos and descriptions. If you feel your shell is significantly different from what was described, please contact me within 7 days, and we will find a thoughtful solution.
A Note on “Change of Mind”: As each shell is a natural, unique item, I cannot accept returns or exchanges due to a “change of mind.” Please review the photos and dimensions carefully to ensure it’s the perfect “ocean companion” for you.
We are deeply committed to sustainable and ethical practices. All our shells are sourced responsibly—never from live-shelled creatures. We support marine conservation efforts and maintain transparency about our sourcing practices.
Coelopleurus mailardii belongs to a group of sea urchins adapted to deeper marine environments, where slower growth and reduced predation often result in thicker, well-formed tests.
Deep-water echinoids are less commonly encountered in the shell trade, making authentic specimens especially valued by collectors and researchers.
